I actually used a cheap teatowel to make this cosy, because I just started sewing things and don't have any fabric yet. So, its possible that you will come across this towel a few more times in my future projects ;)
The little hart on te closure flap was made using OutsaPops tuturial about plastic bag fusing. All sewing and drawing was done by hand, and the hart is just freeform, but I think it turned out pretty ok
